    Area of Science:

    • Nephrology
    • Immunology
    • Pathology

    Background:

    • Immunoglobulin A (IgA) nephropathy is a primary glomerular disease.
    • The complement system plays a crucial role in immune responses and inflammation.
    • Glomerular deposition of immunoglobulins is a hallmark of IgA nephropathy.

    Purpose of the Study:

    • To investigate the role of the complement system in IgA nephropathy.
    • To correlate complement deposition patterns with histopathological findings.
    • To assess the prognostic value of complement system analysis in IgA nephropathy.

    Main Methods:

    • Histopathological examination of kidney biopsies.
    • Immunofluorescence staining for immunoglobulin and complement deposition.
    • Analysis of complement pathway activation components.

    Main Results:

    • A strong association was found between complement deposition and glomerular tissue destruction.
    • Alternative complement pathway components were prominently linked to IgA deposition.
    • Classical complement pathway components may correlate with IgG and IgM deposition.

    Conclusions:

    • Complement system activation is closely involved in the pathogenesis of IgA nephropathy.
    • Specific complement pathways are differentially associated with IgA, IgG, and IgM deposition.
    • Complement analysis offers valuable insights into tissue damage and prognosis for IgA nephropathy patients.
